iPhone 6 may arrive in September

More rumours about Apple's upcoming iPhone 6 are started to emerge, with the latest reports speculating that the Cupertino flagship will arrive in September.

This is according to Japanese site Nikkei, which states that Apple is "likely" to offer the next iPhone in two sizes - a 4.7-inch and a 5.5-inch version.

Various rumours have suggested that production for the next iPhone is stepping up, indicating that the product's release won't be that far away. Many had speculated that the iPhone 6 would arrive sometime after June - following the company's timescale for flagship releases.

The expected screen sizes would be a significant change for Apple, which has managed to keep its screen sizes compact despite a number of its rivals maxing out the display on their handsets.

According to Nikkei sources, mass production of liquid crystal display panels could start in the next quarter and the display resolution of the iPhone 6 will be much higher than current models.
